Der den Gegenstand der Erfindung bildende Einspannbock vereinfacht wesentlich das Umspannen der damit auf der Tischplatte von Metall-Hobel-, Fräs-, Feil- und anderen Werkzeugmaschinen festgeschraubten Werkstücke zum Zweck der Bearbeitung ihrer verschiedenen Flächen. Das zwischen zwei solchen Spannböcken eingespannte Werkstück kann ohne Lösen der durch mit dem üblichen Schwalbenschwanzkopf versehene Feststellschrauben in einem Spannschlitz des Tisches festgestellten Spannböcke zum Bearbeiten einer anderen Fläche umgestellt werden, weil die Druckschraube jedes Spannbockes mit einem um ihre Achse drehbaren Kopf gegen das Werkstück wirkt und weil diese Druckschraube aufserdem, ohne dafs sie gelöst zu werden braucht, in einem Schlitten senkrecht zu ihrer Achse auf und nieder verstellt werden kann.The clamping frame forming the subject of the invention considerably simplifies re-clamping the one on the tabletop of metal planing, milling, filing and other machine tools screwed workpieces for the purpose of machining their various surfaces. That between two such brackets The clamped workpiece can be removed with the usual dovetail head without loosening it provided locking screws in a clamping slot of the table fixed clamping brackets for processing another Area to be converted because the pressure screw of each clamping block with one around their Axis rotatable head acts against the workpiece and because this pressure screw also, without needing to be loosened, in a slide perpendicular to its axis on and can be adjusted down.
Die beiliegende Zeichnung veranschaulicht die Erfindung.The accompanying drawing illustrates the invention.
Fig. ι zeigt den Spannbock in Seitenansicht, Fig. 2 in Vorderansicht,Fig. Ι shows the clamping block in side view, Fig. 2 in front view,
Fig. 3 in Aufsicht,Fig. 3 in plan view,
Fig. 4 die Befestigung des an der Druckschraube drehbaren Kopfes durch einen Schnitt nach A-B (Fig. 1),Fig. 4 shows the attachment of the head rotatable on the pressure screw through a section according to AB (Fig. 1),
Fig. 5 einen Einzeltheil.Fig. 5 shows a detail.
Der in der üblichen Weise mit der in den Spannschlitz des Maschinentisches einzuführenden Feststellschraube α versehene Einspannbock b führt in dem rechteckigen Ausschnitt c seines senkrechten Schenkels den Schlitten d, der die wagerechte Druckschraube e mit ihrem beweglichen Kopf f trägt. Dieser ist in der Weise um die Schraubenachse drehbar befestigt, dafs das ausgebohrte Schraubenende einen dem Kopf f angearbeiteten Drehzapfen g aufnimmt und ein schräg durch eine entsprechende Bohrung des Schraubenendes getriebener Stift h in eine Ringnuth dieses Drehzapfens eingreift. Der Ausschnitt c des Bockes wird durch eine mit Schrauben i befestigte und in der Mitte mit dem Gewindeloch k versehene Platte / (Fig. 5) geschlossen, welche die Stellschraube m trägt. Diese ist mit dem Schlitten d durch den Kopf η und die über denselben greifende getheilte, dem Schlitten aufgenietete Platte ο drehbar verbunden und gestattet die Verstellung der Druckschraube e senkrecht zu deren Achse. The clamping bracket b , which is provided in the usual way with the locking screw α to be inserted into the clamping slot of the machine table, guides the carriage d in the rectangular section c of its vertical leg , which carries the horizontal pressure screw e with its movable head f . This is attached rotatably about the screw axis in such a way that the drilled screw end receives a pivot g machined to the head f and a pin h driven obliquely through a corresponding hole in the screw end engages in an annular groove of this pivot pin. The section c of the block is closed by a plate / (Fig. 5) which is fastened with screws i and has a threaded hole k in the middle and which carries the adjusting screw m. This is rotatably connected to the slide d through the head η and the divided plate ο riveted onto the slide and grips over the same and allows the adjustment of the pressure screw e perpendicular to its axis.
Wird ein Werkstück zwischen zwei solchen in einem Spannschlitz des Tisches festgestellten Spannböcken eingespannt, so kann es frei um die Achse der beiden Druckschrauben gedreht werden, ohne dafs deren Lösen erforderlich wäre.If a workpiece is found between two such in a clamping slot of the table Clamping blocks clamped so it can be rotated freely around the axis of the two pressure screws without it being necessary to solve them.
